Subway Lines in Tokyo
Tokyo has an excellent subway and rail system. It may appear complicated - and it is - at first glance, but there are many English publications available to help you. A free subway map in English is usually provided near the ticket wickets at each subway station.
The available map is this one provided by Tokyo Metro

As the map shows, each station has a station number, distinguished by colors which represent the subway lines. This helps you find which lines to take to reach your destination, maybe. Since subway trains in the city center run every 2 minutes or so during daytime on weekdays, it would not be a serious trouble even if you take a wrong train, as long as you realize quickly. The point is, check the color of the line and the direction when you get on the train.
How to use the Tokyo Subway
Subway lines in Tokyo are operated by 2 companies; Tokyo Metro and Toei Subway (= Tokyo Metropolitan Government), On their official web site, they offer detailed information on how to ride subway and the fares. They also provide a leaflet "Tokyo Metro Guide" in Japanese English, Chinese and Korean languages, available at each subway station.
Subway lines connected to railways
Most of the subway lines in Tokyo extend far out via extensive through services onto suburban railway lines, due to the trackage rights agreement. For example, the Hibiya Line (H) basically runs between Nakameguro(H1) and Kitasenju subway station(H21), but the line is connected to the Tokyu Toyoko Line bounds for Kikuna Station and the Tobu Skytree Line bounds for Tobu Dobutsu-koen (Zoo) Station, to where some Hibiya line trains allow passengers to reach without changing trains.
